The purpose چکیده کاملUsing self-purification of rivers to improve water quality is also the most economical and sustainable way for clean water. In the present study, the QUAL2Kw model is used to investigate water quality and self-purification capacity in Saland mountain river. The purpose of this study is to investigate the water quality of Saland River in relation to drinking and agricultural uses. The qualitative parameters of BOD5, total coliform and phosphate were simulated and compared with field data in January 2018 and August 2019. The results obtained from the model are to a large extent indicative of the real conditions of the river, which indicates the ability of the QUAL2Kw model to simulate qualitative parameters. According to the observational results, parameters of phosphate and total coliform in terms of agricultural use, as well as parameters of BOD5 in the studied period are not considered a threatening factor for aquatic life. In terms of potable use, according to the standard of the European Union, the American Environmental Organization and the national surface water classification of Pakistan, the parameters of BOD5 and total coliform have been observed during the sampling period of this standard. The speed of the river flow has a greater effect on the self-purification of mountain rivers, and the place of pollution of the point source has a very limited effect. According to the results of RMSE and CV parameters, the model has the best fit for BOD5, phosphate and total coliform parameters, respectively. پرونده مقاله -

The hydrodynamic drag force was measured directly by use of loadcell in the presence of flexible vegetation. Accordingly, all experiments were performed in a flume named "knife edge flume" with 8.3 m length, 0.8 m width and a 0.55 m height. Flexible non-submerged vegetation models with 3 densities (30, 50 and 100%) and staggered arrangement in three relative water depths (0.6, 0.8 and 1) were tested. In this study, vegetation density changed with increasing distance and leaf area of models. The results showed that the drag force significantly depends on the density of vegetation as one of the measurable morphological features of the plant. Density results can be used as a useful criterion in estimating the resistance due to the presence of plant roughness in the river. پرونده مقاله -

The sodic ion alongside salin vocalizes the salin-sodic soil and cause divulge in plants growth. So necessary coure of action for the Soil correction by physical and chemical ways such as usage of calsium on the leaching is inevitable. In this study, area soils are digged from deep profiles of 0-20, 20-40, 40-60, 60-80 and 80-100 cm and samples were prepared for proceeds and analysis in the laboratory and calculated values of ECe, SAR, ESP, CEC and etc and chemical and physical properties was discussed. The test experiment method were conducted by randomized complete block design with two treatments (control, gypsum) and 3 replicate plots metal 1*1 m. Amount of water needed for leaching rate of 100 cm and 5 levels (each level was 20cm) were determined. After each step, the samples were taken in the four set of determined depth and experiment was conducted. The study results and their statistical analysis show that gypsum material has not effect on the reduction of amendment SAR, ECe and ESP of soil. This can be due to the solving gypsum of soli as a result of water infilteration in the soil. It is recommended to improve saline and alkaline soils region to neutralize the effect of high sodium lands at least two preliminary rounds will be conducted with salt water (agricultural Drainage). پرونده مقاله
